I have all of the above except for the tuner. I would agree that the Sony SS-3300 speakers are more suited to valve (tube) amps. Upon my retirement I purchased the Icon Audio Stereo ST40-MK3 integrated valve amp.

I must admit my speakers were almost a restoration project when I bought them. I purchased the Sony SS-3300 speakers for €250 two years from a college in Dublin, Ireland. The price reflected their condition as they were in a sorry state and bore the evidence of 40 years of use and abuse.
One important fact was that all the speakers'
rotary wafer switches were in the same setting for almost 50 years and had
badly oxidized inside the cabinets. They all had to be reconditioned and two will eventually be replaced in one cabinet if I cannot track down compatible wafers. Furthermore, when I had both speakers tested I learned that the 50 year old
condensers (capacitors) in the crossover filters of both cabinets were under-performing. I decided not replace the condensers (capacitors) for two reasons. One, the cost of the original components was prohibitive and secondly, according to the experts even genuine unused condensers of that vintage deteriorate on the shelf over time.
I was offered
€2,400 for the Sony amp, deck and speakers by a English doctor last May. He increased his offer to
€2,700 last September together with €300 extra for my return ferry ticket to Holyhead. I declined his offer.
I hope that gives you some idea of what you should offer bearing in mind that my speakers are definitely not in mint condition..
